Unity Linux 20.1070a Security Update: kernel (UTSA-2025-391705)

high Nessus Plugin ID 266755

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-391705 advisory.

 In the Linux kernel, the following vulnerability has been resolved:

 drm/amd/display: Fix potential index out of bounds in color transformation function

 Fixes index out of bounds issue in the color transformation function.
 The issue could occur when the index 'i' exceeds the number of transfer function points (TRANSFER_FUNC_POINTS).

 The fix adds a check to ensure 'i' is within bounds before accessing the transfer function points. If 'i' is out of bounds, an error message is logged and the function returns false to indicate an error.

 Reported by smatch:
 drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:405 cm_helper_translate_curve_to_hw_format() error: buffer overflow 'output_tf->tf_pts.red' 1025 <= s32max drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:406 cm_helper_translate_curve_to_hw_format() error: buffer overflow 'output_tf->tf_pts.green' 1025 <= s32max drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_cm_common.c:407 cm_helper_translate_curve_to_hw_format() error: buffer overflow 'output_tf->tf_pts.blue' 1025 <= s32max

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
